摘　　要：龙得岗铜砷矿发育在年木耳杂岩体西南边缘,区域构造部位属南秦岭—大巴山—南大别山新元古代-早中生代裂陷大陆边缘,次级构造为双朋喜—新堡复背斜西南翼,主构造线方向呈北西向。该复背斜带由石炭系、二叠系、三叠系海相碎屑岩及碳酸盐岩组成,沿复背斜主构造线方向,印支—燕山期岩浆活动十分强烈。Longdegang copper arsenic deposit is developed in the southwest edge of nianmu'er complex.The regional structure belongs to the Neoproterozoic early Mesozoic rift continental margin of South Qinling Dabashan South Dabie Mountain.The secondary structure is the southwest wing of Shuangpengxi Xinbao anticline,and the direction of the main structural line is NW.The complex anticline belt is composed of Carboniferous,Permian and Triassic marine clastic rocks and carbonate rocks.Along the main structural line of the complex anticline,Indosinian Yanshanian magmatism is very strong.
